Many of NASCAR's stars have taken home the $1 million prize at the Sprint All-Star Race. Jimmie Johnson has won it four times (including the last two), Jeff Gordon has won three times and eight other active drivers have done it once. So who is left? USA TODAY Sports' Jeff Gluck picks four drivers who could breakthrough Saturday night at Charlotte Motor Speedway:

Kyle Busch

Busch is second to Johnson in All-Star race laps led (201) among active drivers. But he's never won an All-Star race or any Sprint Cup Series race at Charlotte in 28 tries. Busch is clearly capable of going to victory lane, given his Charlotte success in other series: Eight Nationwide wins and five Truck wins. Perhaps Saturday could be the time when $1 million helps him forget high-profile clashes in the All-Star Race with brother Kurt (2007) and Joe Gibbs Racing teammate Denny Hamlin (2010).

Tied with Busch for the most All-Star top-10s (four) without a win, Hamlin could continue to show his team is headed in the right direction following a key win at Talladega Superspeedway two weeks ago. Though he has never won a points race at Charlotte, Hamlin has seven-top-10s in a row there dating to 2010.

The Team Penske driver is Charlotte's most recent winner – he went to victory lane in October's Bank of America 500 for his only win of the 2013 season. But Keselowski hasn't had much All-Star success. His average finish of 13.2 rates as one of the worst among the drivers in Saturday night's race – this despite a second-place finish in 2012. He completed just two laps in last year's race before a transmission problem took him out. Surely, the 2012 Sprint Cup Series champion's All-Star fortunes will improve at some point.

Though he's only been in three All-Star Races, Logano has the best average finish of any driver (4.3). He's already won two races this season and Team Penske is strong on intermediate tracks such as Charlotte -- Logano has finished first and fourth in the past two 1.5-mile track races, respectively. It wouldn't surprise anyone if Logano continued his strong year by winning on Saturday night.

Sprint Showdown: The last-chance race known as the Sprint Showdown moves from Saturday to Friday this year, and it comes with an All-Star invitation for three more drivers: the top two finishers in the race plus the winner of a fan vote. The 2013 fan vote winner was Danica Patrick. Those three drivers will compete in qualifying instead of starting from the back, as in previous years.

All-Star qualifying: This moves from Friday to Saturday and will set the All-Star Race lineup. It consists of three laps with a mandatory four-tire pit stop — but there's no pit road speed limit, which makes things interesting. Cars go out individually.

Sprint All-Star Race: This consists of five segments, but you'll need a calculator to keep track of what's going on. The average finishing position in each of the first four segments (20 laps each) will determine how the cars line up for a mandatory four-tire pit stop before the fifth segment. The order of the cars coming off pit road will then set the order for the final 10-lap shootout.
